The stripes visible on most of the tubes are a result of a layup technique that involves laying reinforcing strips circumfrentially around the tubes. The strips add strength and stiffness without much weight, like "built in ribs," said Guru marketing manager Phil Pinskey. Photo: Caley Fretz | VeloNews.com

Guru launched three new Photon models at NAHBS, led by the top-tier Photon HL. The HL frame weighs only 670 grams (claimed) for a 54cm size, and represents the culmination of a two-year development cycle. It is a redesign of the old Photon from the ground up, with new tube shapes and carbon technology used throughout. Photo: Caley Fretz | VeloNews.com
